The AH-D5000 has been designed for music lovers who want to enjoy a realistic sound in complete peace.  The enclosures employ housings made of natural wood Mahogany with superior acoustic characteristics that are rich with a broad, natural sound.  Mahogany is a very popular material for drum making and guitars because of its great integrity and capability to produce very dark, warm tones compared to other more common wood types like maple or birch.  Along with its acoustic characteristics, mahogany's light weight makes it an excellent headphone material as well.

Microfiber has been used to form the diaphragm so that it faithfully reproduces the sonic details and delicate reverberations that occur in concert halls.  The size of the Microfibers is approximately 1/100 that of natural cellulose used in ordinary diaphragms, and with this density, transmission rates are increased.  In comparison, Microfiber diaphragms are (x20,000) and natural cellulose fiber diaphragms are (x150).

The Acoustic Optimizer provides optimum acoustic characteristics by adjusting the sound pressure balance in front of and behind the diaphragm.  This makes the sound more dynamic, provides clear bass, and also keeps balance at low to mid frequency ranges.

The cable used is made of high purity 99.9% 7N OFC cable and employs an aluminum connector cover and a cloth mesh jacket.  High-quality cables of equal length for the L/R channels are used to maintain optimum sound quality and performance.

Additionally the AH-D5000 headphones use a light-weight magnesium frame.  This frame lets listeners enjoy maximum comfort during extended listening sessions.
